What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Severe glenoid bone loss in primary or revision reverse total shoulder arthroplasty presents significant surgical challenges. Patient-specific 3D-printed glenoid implants offer customized fixation strategies for complex anatomical deficits, including modified peg designs, additional screws, and proprietary ingrowth surfaces. Despite promising early results, concerns regarding cost, surgical accuracy, and long-term stability remain. Methods: This retrospective study evaluated clinical and radiologic outcomes in patients with severe glenoid bone loss who underwent primary or revision reverse total shoulder arthroplasty with a custom three dimensional-printed glenoid implant (restor3d) by a single surgeon (December 2022-July 2024). Demographics, surgical indications, implant specifications, patient-reported outcomes, imaging, and complications were collected. Patients with and without complications were compared using Mann-Whitney Results: Eighteen patients (11 women, 7 men; median age 69 years [interquartile range, 67-77]; mean follow-up 18 ± 7 months) were included. Five patients underwent primary surgery and 13 underwent revision procedures, including 7 (39%) staged revisions. Complications occurred in 27.8% of patients: broken inferior or posterior screws (n = 1) and clinical implant failures, including broken central posts or fibrous ingrowth along the post (n = 4). The 4 patients with implant failure required explantation and revision at a mean of 21.7 months. Patients with complications reported greater post-operative visual analog scale pain ( Discussion: Custom 3D-printed glenoid implants show potential for addressing severe glenoid bone loss with patient-specific designs that enhance initial stability. Total screw engagement volume was significantly greater in constructs without complications (
